Over the past few months Nokia has been accepting entries for their Mobile Games Innovation Challenge, with the winner receiving 40,000 euros to develop their game. If you're thinking of entering you'd better get your skates on as the closing date is the 20th of August. Just to emphasise, they don't want actual games or code, what they're after are detailed game concepts including a text description and optionally mockup screenshots and video too. This compo is only open to game development professionals however.
